My composition consists of the following ingredients, combined in the proportions stated, viz: dust from the combustion-chamber of boilers, ten bfishels; sawdust, twenty bushels; cocoannt fiber, two bushels; fire clay, one I5 bushel; lime, one-half bushel; alum, four pounds. These ingredients are to be mixed with water into a paste.

25 it will save fifty per ceutum in fuel.
